CORNER-POST FOR BOX-LIKE STRUCTURES.

Patented June 25, 1912.

Serial No. 691,482.

To all whom it may concern:

Be it known that I, WVILLIAM ZABEL, a

citizen of the United States, residing at: Edgewood Park, in the countyof Allegheny and State of Pennsylvania, have invented certain new anduseful Improvements in Corner-Posts for Box-Like Structures, of whichthe following is a specifica tion.

My invention relates to corner posts for supporting the side-pieces ofbox-like structures.

I will describe one form of corner post embodying my invention, and thenpoint out the novel features thereof in claims.

In the accompanying drawings, Figure 1 is a perspective view showing oneform of corner post embodying my invention. Fig. 2 is a top plan viewand Fig. 3 is a side elevation of the corner post shown in Fig. 1. Figs.4c and 5 are views showing separately two of the parts comprised in thedevice shown in the preceding views.

Similar reference characters refer to similar parts in each of theseveral views.

Referring to Figs. 1, 2 and 3, I have here shown one corner of abox-like structure of which 11 is a base, 12 is a top, and 20, 20 aretwo adjacent side-pieces. In Figs. 1 and 2 the top 12 has been removedto more clearly show the structure of the corner post. 10 is a studsecured in both the base and the top; as here shown this stud isprovided adjacent one end with a shoulder 13 so that this end may beriveted to the base 11; the other end of the stud is drilled and tappedto accommodate a screw l t by means of which the stud may be secured tothe top 12.

15 is a side-supporting member, shown separately in Fig. 4. This memberis in practice preferably a stamping from a piece of rigid sheet metal.The piece is punched with several pairs of slits 16 and is then bentinto substantially the shape indicated in Fig. 4, the material betweenthe slits of each pair being bent outwardly to form bands 17 which areof such size as to accommodate the stud 10. The portions of the member15 lying on each side of the stud serve as supports for the side-pieces20, 20, hence theangle through which the member is bent depends upon thedesired angle between the side-pieces; as here shown the device is thecorner post of a square box, hence this angle is 90 degrees.

In order to hold the side-pieces 20, 20

firmly against the supporting member 15 I provide a spring member 18,which member is preferably a stamping from a flexible and springymaterial such as a phosphor bronze or spring steel; this member isillustrated separately in Fig. 5. This member is bent into substantiallythe shape shown in Fig. 5, and is provided with apertures 19, 19 of suchsize as to accommodate the bands 17, 17

of the supporting member 15.

To assemble the form of corner post here shown, the stud 10 is firstriveted in the base 11, the spring member 18 and the supporting member15 are then fitted together with the bands 17 projecting through theapertures 19, and the two members are then slipped 'over the stud. Theside-pieces 20, 20 are then slipped into position between the twomembers as shown in Figs. 1 and 2 and finally the top 12 is secured tothe stud by means of the screw 14.

The supporting member 15 is of material which is sufficiently rigid tomaintain the side-pieces 20, 20, in proper position. The spring member18 is preferably of material which will yield sufticiently to compensatefor variations in thickness of the sidcpieces 20, 20 and which alsopossesses sufficient springiness to exert considerable pressure upon theside-pieces and thereby form a tight and secure structure.

A device embodying my invention is particularly adapted for use as thecorner post for supporting the glass side-pieces of the box-likestructures which are employed to inclose the operating parts of railwaysignaling and other relay devices.

Although I have shown and described only one form of corner postembodying my invention, it is understood that various changes andmodifications may be made therein within the scope of the appendedclaims without departing from the spirit and scope of my invention.

Having thus described my invention, what I claim is 1. A corner post forbox-like structures comprising a stud, a side-piece supporting member,means for securing said member to the stud, a spring member supportedalso by the stud, and side-pieces held between the two said members.

2. A corner post for box-like structures comprising a stud, a side-piecesupporting member and a spring member, means embodied in said membersfor interlocking them and for securing them to the stud, andIs)ide-pieces held between the two said memers.

3. A corner post for box-like structures comprising a stud, a side-piecesupporting member shaped to partially encircle the stud and providedwith bands encircling the remainder of the stud, a spring memberpartially encircling the stud and located between the stud and the bodyof the said supporting member and having apertures to accommodate thesaid bands, and side-pieces held between the two said members.

A. A corner post for box-like structures comprising a stud, a side-piecesupporting memberprovided with bands adapted to secure the member to thestud, a spring member located between the stud and the said supportingmember and provided with apertures to accommodate the said bands, and

side-pieces held between the two said members.

5. A corner-post for box-like structures comprising a stud, a side-piecesupporting member shaped to partially encircle the stud and providedwith pairs of slits the material between the slits of each pair beingbent outwardly to form bands which encircle the remainder of the stud, aspring member partially encircling the stud and located between the studand the body of the supporting member and provided with apertures toaccommodate the said bands, and side-pieces held between the two saidmembers.

6. A corner post for box-like structures comprising a stud 10, asupporting member 15 provided with bands 17 to secure it to the stud, aspring member 18 provided with apertures 19 'to accommodate the bands17, and side-pieces held between the member 15 and the member 18.

In testimony whereof I afiix my signature in presence of two witnesses.

. WILLIAM ZABEL.
